While at Hogwarts, I awakened the Middle-earth Survival System, but something about the system was a bit off… [You received your Hogwarts acceptance letter—Main Quest: The Fellowship of the Ring!] [You didn't go to Gryffindor, but instead joined the Hufflepuffs, a bunch of gluttons—Reward: Hobbit Racial Talents (Stealth + Gluttony)!] [You refused Malfoy's handshake—Reward: Strength +1 (That's how you deal with fallen elves!)] [You wielded your wand powerfully—Reward: Two-handed Sword Strike (Magicians should have some Strength)!] The system actually thought I was in Middle-earth from Lord of the Rings?! …Years later. Voldemort led his army of Death Eaters to attack Hogwarts. Before the Dark Lord could even finish reciting Avada Kedavra, Rowe Baggins was already in front of him, wielding Narsir, and with a backhand…

"You'd better find something to eat before dark." This was the first thing Kane heard after running away from the Dursleys. Okay, I knew I hadn't completely escaped the Famine world... but thankfully, his ability to manipulate his shadow in Famine still remained, not only saving him from starving to death after running away and being killed by invading shadow creatures at night, but also bringing him other benefits in this world. Wait... what does "for using dark magic in front of Muggles, now granted a VIP status in Azkaban" mean? Dumbledore blushed and quickly snatched the envelope from Kane's hand, replacing it with another. A Hogwarts acceptance letter, this time it's right.

Roger traveled to the world of Harry Potter.

The game started on hellish difficulty; he became the apprentice of an old, powerful, and extremely temperamental dark wizard. Just as he was cautiously serving this unpredictable mentor, he unexpectedly discovered that the bio-computer he had developed in his previous life had also transmigrated with him!

From then on, Roger's magical training began with the three Unforgivable Curses! "Analysis of the Imperius Curse complete." "Begin observing Professor Quirrell."

Years later, when the Daily Prophet was preparing to write a legendary feature on Mr. Roger Lewis, prominent figures in the wizarding world spoke out:

Professor McGonagall (with a serious expression of amazement): "Without a doubt, Mr. Lewis is an unprecedentedly outstanding graduate in the history of Hogwarts." Dumbledore (his wisdom gleaming behind his half-moon spectacles): "I must admit that no one understood the nature of magic better than Roger. Not even the four founders of Hogwarts." Voldemort (in a complex tone): "It is well known that I made indelible contributions to Roger's magical research..."

Rita Skeeter (writing furiously with her quill pen, her eyes gleaming with gossip): "Mr. Riddle, was it the summer before Mr. Lewis enrolled?"

Voldemort (lost in memories): "Sigh...that summer, they invited me to participate in the experiment, though the method was crude...If they had said it was to develop an elixir of immortality, I could have provided tremendous assistance! I wouldn't have needed to go through the trouble of finding the Philosopher's Stone...I still deeply regret missing this opportunity to return sooner!"

"How does it feel to be given the name Rozier?" "Get lost!" "How can you be so heartless!" "Stop with that gloating look. And can you please stop bullying those three little ones and Malfoy? You're practically ruining them!" "Tch, what do you know? You're having fun outside, while I can only find my fun at Hogwarts." These were the days these two shameless rascals spent having fun at Hogwarts.

Having transmigrated into the last bloodline of the Grindelwald family, he initially wanted to live a low-key life, but was forced to bind himself to the "Underworld God System".

From then on, the style of Hogwarts completely went astray.

"Petrify everyone? That's too lame. Come and witness the power of our Zaun petrification!"

"Want to learn the Patronus Charm? First, pay protection money to the system. Avada Kedavra can turn a melon into a rainbow color for you."

Dumbledore looked at the savior, who had been turned into a "henchman," and fell into deep thought: "This kid...maybe he can form the most cowardly villain alliance in history with Tom?"

Until one day, I was cornered by the Dark Lord, and the system suddenly prompted me—"Hey buddy, there's only one guy on the other side, call for reinforcements to take him down!"

A letter from Grandpa arrived from afar, saying there was a farm for me to inherit. So Matthew went and started planting parsnip. But what's with this owl? Hogwarts? Ah, of course, of course, I love Hogwarts' greenhouses! I'm a peaceful farming enthusiast! But, Mr. Voldemort, why are you stepping on my land?

Will Evans wakes up to find himself transported to the world of Harry Potter. Good news: he knows the entire plot. Bad news: he knows nothing but the original story. So, Will decides—to cling to Dumbledore's coattails and achieve a life of effortless success! "Professor, Quirrell has a face on the back of his head!" "Professor, the diary has a mind of its own, burn it with Fiendfyre!" "Professor, don't wear that ring, it'll kill people!" Dumbledore: ...? When the greatest wizard holds the script, Voldemort's Horcruxes face their most disastrous failure in history. In their first year, they prematurely eliminate Peter Pettigrew. In their second year...

The rating is low at the start, don't be scared away! I solemnly swear, this is a divine herb, not poison. Transmigrating to the HP world, Luke awakens the Magic Chef System, harvesting emotional points with delicious food to exchange for rewards.

As for learning magic at Hogwarts? Sorry, you can freely exchange for spell learning speed, potion-making skills, and alchemy experience. With a system, you can really do whatever you want.

Thus, the teachers and students of Hogwarts witnessed the terrifyingly strong yet seemingly unorthodox freshman Luke.

[Congratulations, host! Your Magic Hawthorn Candy Balls have successfully garnered 1000 positive emotion points, easily earning you the Beginner Transformation talent!]

Minerva McGonagall: Didn't the principal say you weren't good at it? You learned it in the time it takes me to twist my hip?

[Congratulations, host! Your magically spicy hot pot has successfully garnered 10,000 positive emotion points, instantly transforming you into a fire god in half an hour!]

Dumbledore: To be able to perform such a move with just a slight glance at my notes... perhaps he's more suited to it than Harry...

[Congratulations, host! Your Magic Lamb Skewers and Lamb Kidneys have successfully garnered 10,000 negative emotion points. You can claim the Dark Lord's Three-Piece Set without any side effects.]

Voldemort: You're just a little wizard from Badger Hill, why aren't you doing your job properly and learning dark magic? Don't I have any dignity?

...

When everyone's stomachs took the shape of Luke's, his magical talent and strength skyrocketed. A chef? Call him the God of Cookery!

The Death Eater was stunned: Oh my god! Run!

He is the real demon king!

Who has ever seen someone catch Avada Kedavra with a spatula?

First grade, Horatio: Headmaster, look, use this scythe of mine to hook out the soul, then lock it in this lamp and roast it with the fire.

Second grader Horatio: Principal, look at this cabbage! It can increase in value infinitely and even kill the basilisk in an instant!

Third grader Horatio: Principal, do you think this soul contract could arm the Dementors into my army of Soul Reapers?

Fourth grader Horatio: Headmaster, look, this gravity magic can pull down meteorites from outer space to strengthen Durmstrang and Beauxbatons College.

Fifth grade, Horatio: Principal, you said if I projected this mark onto the moon, everyone who saw it would be brainwashed into a believer in houttuynia cordata, and the houttuynia cordata I planted in the Forbidden Forest would sell like hotcakes.

Sixth grader Horatio: Headmaster, look! The tree that grows from this seed can convert cosmic energy into magical seeds. Then all of humanity can become wizards, mastering both technology and magic. Conquering the stars will be just around the corner!

Seventh grader Horatio: Principal, look...

Dumbledore: "Enough talk. Take out your wand. It's either you or me today."

(Updates are irregular, written for my own amusement and humor, featuring multiple female characters)

The blue nine-magatama Rinnegan, with a fat, silly and cute duck god standing next to it.

Until one day, Voldemort and his army of Death Eaters surrounded Hogwarts Castle.

Our little Sith was guarding the castle gate alone.

"Tom Riddle, today you will feel what true despair is!"

"Psyduck, Freeze Ray!"

Poor Bellatrix was frozen into an ice sculpture.

"Senjutsu, Wood Release, True Thousand Hands!"

"Susanoo!"

Chen Hao stood on top of a hundred-meter-high Susanoo Buddha, looking down at the shivering Death Eaters below.

"Are you ready?"

Inside the castle.

Luna: "Sith, you're so handsome!"

Hermione: "Harry, are you sure your cousin is human?"

Ron: "Harry, a new generation of Dark Lord is born, although this guy is a bit flat!"
